Standout performance

Rockford Fosgate showcases their fanatical commitment to sonic excellence in the Punch Series of speakers, amps, and subs. If you like to listen to potent, powerful music — and feel it too — Punch components will give you impressive sound that'll stand out in a crowd.

Bulletproof bass

Engineers at Rockford Fosgate designed the P2D4-8 8" subwoofer to dish out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar® fibers used in bulletproof vests so you get the best of both worlds — warm bass that's exceptionally hard-hitting. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass.

Made for heavy excursion

This P2 sub features an extended pole piece and bumped backplate that leaves more room for heavy excursion, so it'll hit deeper lows without "bottoming out." Special venting keeps the copper-clad aluminum voice coils cool through heavy use for consistent bass performance over time.

The dual 4-ohm voice coils allow you to wire the sub for 2-ohm impedance to work with a mono sub amp, or for 8-ohm impedance if you're using multiple subs. The P2D4-8 sub works equally well in a sealed or ported enclosure, so you can choose the kind of bass you want for your system.

To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 375 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.

What's a component sub and why would I want one?

A component sub is simply a speaker that's designed to reproduce bass once it's installed in a compatible enclosure. Think about the impact of a movie soundtrack in a big theater or even in your own home HDTV setup. A component sub can add the same kind of power to the music in your car. And a car sub is not all about the boom that you hear on a street corner (although that's cool too) - you can pair a component sub with your choice of enclosure to get bass just the way you like it, from tight and punchy to fat and loose. And once you experience music in your car with a well-tuned subwoofer, you'll never go back.

Dual 4Ω Voice Coils: The dual 4Ω voice coils offer
wiring flexibility; when wired in parallel the woofer presents a 2Ω load,
when wired in series the woofer presents an 8Ω load.

Steel Basket: The P2D4-8 subwoofer features a StampCast steel
basket for added rigidity.

Compression Terminals: The P2D4-8 features spring post
terminals which accommodate speaker wire up to 10 gauge.

CEA-2031 Compliant: Power handling on the P2D4-8 subwoofer
conforms to CEA-2031 industry standards. This means the subwoofer has the capacity
to handle its rated power under continuous demand, not instantaneous power handling,
that over time, can damage voice coils.

Trim Ring: To improve the cosmetic look, a decorative trim
ring is included that mounts over the flange of the woofer. When using the cast
aluminum trim ring the woofer is first mounted with four screws, then the ring
is placed on top of the woofer, aligning the final four holes of the woofer with
ring. The other four screws are used for these holes to mount the ring and woofer
to the enclosure. Without the trim ring the mounting height of the woofer is
approximately 7/8 of an inch.

Enclosure Compatibility

Sealed Box: Rockford recommends a sealed enclosure with
an optimum internal volume of 0.23 cubic feet (from 0.2 to 0.3 cubic feet is
acceptable). Sealed enclosures provide the most control over a woofer, will
handle a lot of power, and provide accurate sonic reproduction, making them
suitable to all types of music.

Ported Box: Rockford recommends a ported enclosure with an
internal volume of 0.65 cubic feet using one 2" diameter x 8" long
port; this yields a tuning frequency of 38.5 Hz. Ported (or vented) enclosures
typically provide better overall efficiency than sealed so they are suitable
for use with smaller amplifiers, giving you more bass output from less power.
However, this efficiency comes at the expense of very low frequency output
(below 33 Hz).

Rockford Punch 8's

I have yet to hear the subs as my application will be tricky shoe horning them under the back seat of my 04 2500HD quad cab. However if they sound half as good as thy look then they will certainly be impressive. They are overbuilt and massive for an 8" sub.

Pros:Power handling and the DVC's impedance options make wiring very flexible. The trim ring is elegant and again well made.

great sounding

I am building my first system, and choose to get two of these 8 inch Rockford due to space constraints in my crew cab Colorado. The subs sound awesome for being really under powered (planning on getting a bigger amp later) and being in a box that is definitely not the best shape for acoustics. They are not window rattlers, but provide bass and depth to any music

best BOOM for the buck
